The Effect of Implant Distribution on Functional and Patient-Reported Outcomes of Mandibular Overdentures Retained by Four Mini Implants.
Purpose: This study investigated the effects of implant distribution on functional and patient-reported outcomes of patients treated with a mandibular overdenture retained by four mini implants.
Materials and methods: Seventy-four participants received four titanium-zirconium mini implants in the anterior mandible, and the relative position of the implants was assessed in post-treatment computed tomography scans with three reference points in the incisal region and first molars of the overdenture. DICOM files were analysed using Blooming Artefact Reduction filters to allow the visualisation of the mini implants in their three-dimensional position without overlapping bone structures. The implant distribution parameters were the polygon area formed by the four mini implants (implant area), anterior and posterior cantilever extensions, and antero-posterior spread. Outcomes included anterior and posterior maximum voluntary bite force (MBF), masticatory performance (MP), oral health-related quality of life impacts (OHIP-Edent) and satisfaction with the overdenture. Paired t-test, Pearson's correlation test and multiple regression were used for data analysis.
Results: The implant distribution area was the most relevant variable for all functional parameters. The larger the distribution, the better the MP (p = 0.003), and the anterior (p = 0.011) and posterior MBF (p < 0.001). Concerning patient-reported outcomes, no effect of implant distribution was observed (p > 0.05), suggesting that the potential benefit of better distribution may not affect patients' perception of the treatment.
Conclusion: Findings corroborate the influence of implant distribution of the four mini implants on functional parameters and, although the best implant distribution may depend highly on anatomical factors, these parameters should be considered an important prognostic factor for treatment success.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
